instance method

IO::Buffer#each

each(buffer_type, [offset, [count]]) {|offset, value| ...} → self

each(buffer_type, [offset, [count]]) → enumerator

static VALUE
io_buffer_each(int argc, VALUE *argv, VALUE self)
{
    RETURN_ENUMERATOR_KW(self, argc, argv, RB_NO_KEYWORDS);

    struct io_buffer_each_arguments arguments = {
        .self = self,
        .argc = argc,
        .argv = argv,
    };

    rb_io_buffer_lock(self);
    return rb_ensure(io_buffer_each_locked, (VALUE)&arguments, rb_io_buffer_locked_ensure, self);
}

Iterates over the buffer, yielding each value of buffer_type starting from offset.

If count is given, only count values will be yielded.

Example

IO::Buffer.for("Hello World").each(:U8, 2, 2) do |offset, value|
  puts "#{offset}: #{value}"
end
# 2: 108
# 3: 108
